Slow speed and regular disconnecting

[EIGHTIESLAD]

Ive been having intermittent problems with my internet disconnecting - sometimes every 5-9 mins and wondered if it was a faulty modem or router and wondered if someone in the know could take a look at my stats and see if anything was wrong:-

modem: ntl 256
router: belkin n1 wireless router

thanks guys

Stats look fine, could be the router. Try without it for a while

I think you've noise on the line.

Upstream Modulation : QPSK
Time Not Established Time Not Established Critical (3) No Ranging Response received - T3 time-out

Sun Oct 10 17:52:21 2010 Sun Oct 10 17:52:21 2010 Critical (3) No Ranging Response received - T3 time-out

Along with the high jitter.

May be worth contacting technical support.

do they help? or as usual useless...

If you don't contact them then you'll get nothing done.

I have a similar problem 3 pc's on a belkin N router not using wireless all on lan connections and we all get spike drops intermittently
Any help would be appreciated

Both your d/s power level and SNR are very much on the low end and IMO need adjusting.(not getting into the QPSK argument). Ring in and book a tech.

Thanks will ring in tomorrow
